mwifiex records information about various channels as it receives scan
information. It does this by appending to a buffer that was sized
to the max number of supported channels on any band, but there are
numerous problems:
(a) scans can return info from more than one band (e.g., both 2.4 and 5
GHz), so the determined "max" is not large enough
(b) some firmware appears to return multiple results for a given
channel, so the max *really* isn't large enough
(c) there is no bounds checking when stashing these stats, so problems
(a) and (b) can easily lead to buffer overflows
Let's patch this by setting a slightly-more-correct max (that accounts
for a combination of both 2.4G and 5G bands) and adding a bounds check
when writing to our statistics buffer.
Due to problem (b), we still might not properly report all known survey
information (e.g., with "iw <dev> survey dump"), since duplicate results
(or otherwise "larger than expected" results) will cause some
truncation. But that's a problem for a future bugfix.
(And because of this known deficiency, only log the excess at the WARN
level, since that isn't visible by default in this driver and would
otherwise be a bit too noisy.)

40GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to i40e and i40evf only.
Gustavo Silva fixes a variable assignment, where the incorrect variable
was being used to store the error parameter.
Carolyn provides a fix for a problem found in systems when entering S4
state, by ensuring that the misc vector's IRQ is disabled as well.
Jake removes the single-threaded restriction on the module workqueue,
which was causing issues with events such as CORER. Does some future
proofing, by changing how the driver displays the UDP tunnel type.
Paul adds a retry in releasing resources if the admin queue times out
during the first attempt to release the resources.
Jesse fixes up references to 32bit timspec, since there are a small set
of errors on 32 bit, so we need to be using the right calls for dealing
with timespec64 variables. Cleaned up code indentation and corrected
an "if" conditional check, as well as making the code flow more clear.
Cast or changed the types to remove warnings for comparing signed and
unsigned types. Adds missing includes in i40evf, which were being used
but were not being directly included.
Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like
other XDP enabled drivers, so that on dump we can retrieve the attached
program based on the id and dump BPF insns, opcodes, etc back to user
space.
Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor
fields, since they are in little-endian format. Also removed
unnecessary "__packed" to a couple of i40evf structures.
Stefan Assmann fixes an issue when an administratively set MAC was set

10GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to ixgbe only.
Tony provides all of the changes in the series, starting with adding a
check to ensure that adding a MAC filter was successful, before setting the
MACVLAN. In order to receive notifications of link configurations of the
external PHY and support the configuration of the internal iXFI link on
X552 devices, Tony enables LASI interrupts. Update the iXFI driver code
flow, since the MAC register NW_MNG_IF_SEL fields have been redefined for
X553 devices, so add MAC checks for iXFI flows. Added additional checks
for flow control autonegotiation, since it is not support for X553 fiber
and XFI devices.
v2: removed unnecessary parens noticed by David Miller in patch 6 of the
series.
v3: dropped patch 6 of the original series, while we work out a more
generic solution for malicious driver detection (MDD) support.
v4: updated patch 1 of the series with the comments from Joe Perches which
were:
- switched logic to return on error
- return 0 on success
- declare retval as an integer
